This study is going to answer how is humankind nature according to Hobbs views using descriptive analytical method and referring to anthropological ideas of Thomas Hobbs. Then it is going clarify and assess its ethical consequences according to Allameh Tabatabaee's views and its findings. Referring to Allameh Tabatabaee's views in this regard beside the clarification of consequences of Hobbes' views, facilitates comparative study and familiarity with the correct view in each topic. The findings show that human beings in his actions and behaviors in Hobbes view is obedient to his wills and interactions in such a way that even his intellect is under power of his wills and excitements. So Hobbes accepts that to control humans and create compatibility among them, there is no way except common agreement and obedience to the rulers. The result of this approach is to reject any real background for ethical values. In apposite, according to bilateral characteristic of human nature (body and soul) and his intellectual ability to recognize right and wrong, Allameh talks about real background if ethical values, innate right and wrong, justification and demonstrable ethical values. In his view making ethical values and applying them by rulers as Hobbes believes will cause obedience of wil, oppression and social class. And also there would be no guarantee for applying the ethical values. So Allameh is seeking to clarify the topic in a different way.
